KING, OF \VATEE-BURY, CONNECTICUT, ASSIGNOR T SCOT/ILL I /LANUFAC- TUBING COMPANY, OF HATERBURY, CONNECTICUT, A CGEPORATION OF CONNECT- IGUT TACK FASTENED BUTTON Application filed September 30, 1931.

This invention relates to a metal button which is designed to be applied to goods by means of a tack, the point of the tack being upset or clinched within the button in the act 5. of setting and thus insuring permanent union of the button and tack.

The object of the invention is to provide a one piece metal structure which may constitute the entire button, or which may have a cap or top for serving utilitarian as well as ornamental purposes, or which may serve as a combined filler, anvil and tack anchorage in a button having an added back and cap or top. In other words, the structure itself contains a head, an anvil and an anchorage, and is, in fact, a finished button, useful as such, and adapted to receive or have applied to it any desired auxiliaries and finish.

The invention consists of a button, formed from a blank of suitable sheet metal, having a plurality of radial arms, the blank being cupped and thereafter drawn or pressed to shape to form a fiat head or top, from the back of which projects a tubular shank or hub formed of the radial arms. with their terminals turned toward each other to partly close the bottom of the shank or hub and to form an anchorage for the upset or clinched part of the fastening tack, the head or top not only forming the face of the button but also an anvil for upsetting or clinching the shank of the fastening tack; the structure thus defined being adapted for use also with an added finish cap, or as forming the filler, anvil and anchorage in a button having a hubbed back and a finish cap or top; as I will proceed now more particularly to explain and finally claim.

In the accompanying drawing, illustrating the invention, in the several figures of 49 which like parts are similarly designated, Figure 1 is a plan view of the blank having a plurality of radially arranged arms. Fig. 2 is a perspective view illustrating the cupping of the blank. Fig. 3 is a bottom plan view illustrating the operation of forming the embryotic shank or hub. Fig. 4 is an elevation of the structure shown in Fig. 3. Fig. 5 is a side elevation of the succeeding step of flattening the head and drawing the arms into 59 cylindrical form.

Fi g. 10 is. an elevation of the finished button showing in as section a cap applied thereto. Fig. 11 is a bottom plan view of Fig. 10. Fig. 12 shows the button used as a filler, anvil, and anchorage employed as such in an exterior finish of a hubbed back and the finish cap applied to the back. Fig. 13 is a cross section of the structure shownin Fig. 12 but taken at right angles to the illustration shown in Fig. 12. Fig. 14 is a cross section illustrating the mode of applying the button'of Figs. 12 and 13 to an object; it being understood that this Fig. 14 also illustrates a mode of applying the button of Figs. 8 and 9 and Fig. 10 to an object. 7 V

In forming the button of this invention, 1 use a circular blank 1, having a plurality of arms 2 projecting therefrom radially. This blank may be of relatively thick and hard metal. The next step in the formation of the button consists in cupping the blank of Fig. 1 so as to draw down a portion of the circular part, and the arms, as shown in Fig. 2. The next step, as illustrated in Figs. 3 and 4 consists in drawing the arms and the cupped portion toward each other into an embryotic back and shank or hub, the adjacent edges of the arms eing brought into substantial contact. The next operation is illustrated in Fig. 5, in which the head is finished and the arms drawn into a substan- 8e tially cylindrical shape. The next operation as shown in Figs. 6 and 7 consists in turning in the terminals 3 of the arms so as to contract the space between them. The next step in the operation, as shown in Figs. 8 and 9. consists in drawing these inturned terminals into a closer approach, so as to form the bottom a of the shank or hub, with an opening 5 to recelve the shank of the fastening tack, as illustrated in Fig. 14.

This last operation as shown in Figs. 8 and 9 produces a completed button, which may be used as such, or have applied to it any suitable finish or ornament, and it is adapted to x I Q be secured to an Ob ect, such as represented A anvil, and anchorage.

at 6 in Fig. 14, by means of a tack 7, the shank 8 of which Is passed into the button through the opening 5 and is upset as at 9 against the anvil face of the top or head of the button and curled over within the hub or shank so as to find an anchorage against the bottom 4 of the shank or hub.

The button, Fig. 9, may have applied to it an added cap or finish 10, of ornamental or other character, and such cap may be of relatively thin metal.

As shown in Figs. 12, 13 and 14, the button of Fig. 9 maybe encased in a hubbed back 11, and therein serve as a combined filler, Such a hubbed back may have any suitable finish cap 12 applied to it.

I am aware that one piece buttons are old in the art, such buttons being made by dieing out rod-like stock, and also by stamping or pressing sheet metal; and I am also aware that it is old in the art to use a combined, filler, anvil, and anchorage made of sheet metal and mounted in a back provided with a cap; but I am not aware of any prior one piece button formed as herein explained.

Variations in the details of construction are permissible within the principle of the invention and the claims following.

What I claim is 1. A button, having a solid top provided with arms drawn down into substantially lateral contact to form a cylindrical shank or hub, the terminals of the arms turned in toward one another to form a bottom having an opening for the reception of a tack fastening, the entire button being formed of a single piece of met-a1 drawn or pressed into shape.

2. A button, having a solid top provided with arms drawn down into substantially lateral contact to form a cylindrical shank or hub, the terminals of the arms turned in toward one another to form a bottom having an opening for the reception of a tack fastening, the structure being formed of a single piece of metal drawn or pressed into shape.

3. A button, having a solid top provided with arms drawn down into substantially lateral contact to form a cylindrical shank or hub, the terminals of the arms turned in toward one another to form a bottom having an opening for the reception of a tack fastening, the structure being formed of a single piece of metal drawn or pressed into shape, and a finish cap applied to said structure, the said one-piece structure forming a combined filler, anvil and anchorage.

4:. A button, having a solid top provided with arms drawn down into substantially lateral contact to form a cylindrical shank or hub, the terminals of the arms turned in toward one another to form a bottom having an opening for the reception of a tack fastenmg, the structure being formed of a single the arms extending inwardly to term the bottom of the hub or shank, an opening'being left in the bottom of the shank for the passage of the shank of a fastening tack.

In testimony whereof I have hereunto set my hand this 28th day of September, A. D.

GEORGE A. KING.
